My present invention relates to machines for winding fabrics insuperimposed layers upon a core but it will be apparent in the followingdcta 'cil description of the inven- 5 tion, that it may beadvantageously used in various other types of machines where problemsare presented whicn the present invention capable of meeting. Theinvention will be described as applied to a winding malo chine and fromthis description the applicability of the invention to other kinds ofmachines will be appa ent.

Winding machines by means of which various fabrics are wound insuperimposed 15 layers on a core are commonly used, for instance, forwinding long strips of fabric, often of several feet in width, upon acore of cardboard tubing, preparatory to placing the Wound fabric on acutting machine to cut 21} it into a large number of coils of but afraction of the width of the original body of wound fabrics. t isnecessary that the shaft of the winding machine be made detachable inorder that it may be removed, first for the purpose of receiving thecardboard or other tube thereover which is to constitute the core forthe fabric coil and, secondly, for the purpose of removing the body offabric and its core from the shaft after the winding opera- 39 tion hasbeen completed.

Thus, the shaft must be removed once and sometimes twice for eachwinding operation. Whereas it is not very difficult to remove the fabricshaft from the machine when it has no load on it, as when the shaft isto receive a core thereon, it is difficult to remove the shaft after thewinding operation has been completed and it has the heavy body of fabricon it.

Several devices have been heretofore used for making the fabric shaftdetachable from the machine but they have been difficult and slow touse, by the same person handling the i body of fabric. The object of thepresent invention is to provide a chuck device for detachably holdingthe fabric shaft in the machine and which will permit the operator toremove the fabric and shaft from the machine after each windingoperation, by the Serial No. 506,893.

the chuck. The chuck,

in fact, may be caused to release the shaft by the manipulation of thelatter, leaving the operator with the full use of both hands formanipulating the body of fabric, which latter also carries the core andthe fabric shaft with it. The operator is thus not liable to drop theheavy body of goods while removing it from the machine and the removingoperation, in addition to being less troublesome and less of a strain onthe operator, makes it possible to remove the body of fabric from themachine in less time.

The operation of replacing the fabric shaft on the machine after it hasbeen removed from inside the body of wound fabric, preparatory toanother winding operation, is also simplified, and the operator mayreturn the shaft to the chuck merely by manipulating the shaft itself.device, while accomplishing the The present results stated, isnevertheless capable of holding the fabric shaft and its load veryfirmly and securely so that the shaft will not be released by the chuckexcept when manipulated for that purpose; in

other words, the shaft and its load will not be accidentally detachedwhile the winding operation is being performed.

The present device is also very simple, dependable and inexpensive.

The present invention is concerned only with the removable shaft and itschuck and only brief reference will be made to other parts of themachine.

In the drawing I have illustrated a simple winding machine having aframe composed principally of end standards 1, 2 which are connectedrigidly with each other by tie rods 3 and by the beam 4 on which lattermost of the operating parts are mounted.

There is a shaft 5 ournaled in a long hearing 6 cast integral with theend standard 2, and it has a pulley 7 which is driven by a belt80perated from any source of power. The hub of this pulley has anintegral sprocket 9 over which an endless chain 10 travels. This chainalso trave s over the sprocket 11 which is revolvable on a shaft 12mounted on a bracket 13 which latter is fixed on the beam 4 of the frameand extends upwardly to form a support for the parts at one end of thefabric shaft. The hub of the sprocket 12 carries a gear 1% which mesheswith and drives a gear 15 which is mounted upon the shaft 16 which is journaled in a bearing member 17 on the upper end of the bracket 13.

The shaft 16 is revolvable in thebearing 17 but it is prevented fromshifting axially in one direction by the gear 15 which abuts against oneend of the bearing 17 and in the other direction by the sleeve 18 whichabuts against the other end of this bearing. The shaft carries one partof the complete chuck for the fabric shaft. 3

This portion of the chuck consists in part of the sleeve 18 whichsurrounds one end of the shaft 16 and to which it is secured by the in19 passing through the sleeve and shaft. The end of the shaft 16 whichprojects into the sleeve 18 is provided with a slot 20 to receivetherein the reduced and flattened end 21 of the fabric shaft 22.

This reduced end of the fabric shaft is adapted to slide into the openend of the sleeve 18 with the flattened projection 21 entering the slot20 in the end of the shaft 16 so that one end of the fabric shaft issupported by the sleeve and the fabric shaft is compelled to revolvewith the shaft 16 when the projection 21 engages in the slot 20. Theshoulder 23 near the end of the fabric shaft is adapted to abut againstthe outer end of the sleeve 18 and, as above stated, the shaft'16 has noaxial movement, at least in the form of the invention hereinillustrated. v

At the opposite end of the frame there is a bracket 24 mounted on thebeam 4 and extending upwardly, parallel with the bracket 13. Thisbracket has at the top a bearing 25 in which a shaft 26 is mounted inaxial alignment with the shaft 16 at the other end of the machine. Theshaft 26 may slide horizontally in the bearings 25 but it is preventedfrom revolving therein by a screw 27 threaded through the bearing 25 andserving as a key in co-operation with the keyway 28 in the shaft 26 toprevent the latter from revolving. It is not absolutely necessary thatthe shaft 26 be prevented from revolving but it is desirable in orderthat the fabric shaft may be disengaged by the same angular movementeach time.

The shaft 26 has a collar 29 fixed to it by a set screw 30 and thiscollar is adapted to abut against one end of the bearing 25 to limit theaxial movement of the shaft in one direction, i. e, toward the oppositeshaft 16.

There is a coiled spring 31 surrounding the shaft 26 and it is adaptedto be compressed between one end of the bearings 25 and a head 32 whichis mounted on the outer, free end of the shaft 26 and fixed thereto by aset screw 33. The purpose of this spring is to permit but resist themovement of the shaft 26 to the left in Figure 3.

There is mounted in the bore 34 in the outer or projecting end of thehead 32 a gimble ring 35 which is pivotally held by the oppositelydisposed pivot screws 36 which screw through the wall of the head 32 andhave smooth, bearing ends extending into apertures 37 in the ring. Thering is thus mounted to turn or swivel on the pins 36 to a limitedextent. It is preferable, though not necessary, that the ring swivel. ona vertical axis as shown and the axis cannot change because the shaft 26to which the head is secured is prevented from turning by the key 27 andkeyway 28.

The ring 35 forms the bearing for one end of the fabric shaft 22 and itis preferably lined with a bushing 38 in which the fabric shaftrevolves.

Operation Assuming the fabric shaft is in position in the machine asshown in Figure l, and it is desired to remove it from the machine toreceive over it a core for the coil of fabric. Assuming that theoperating mechanism is stopped, i. e., assuming that the source of powerwhich drives the belt 8 is stopped, the fabric shaft may be removed asfollows: The shaft is grasped by the hands of the operator whothenpresses the fabric shaft toward the left in Figure 1 or to theposition shown in Figure 2.

This movement disengages the end 21 of the shaft from the end of theslotted shaft 16 and from the sleeve 18 and thus frees one end of thefabric shaft. During this axial shifting of the fabric shaft it presseson the head 32 and forces the latter, together with the shaft 26, towardthe left, as shown in Figure 2. in order to permit one end of the fabricshaft to be disengaged from the sleeve 18. When the parts are in theposition shown in Figure 2 the fabric shaft may be turned because thebearing member, i. e., the ring 35, may turn on the pins 36 and thisturning of the fabric shaft will carry the right hand end thereof out ofalignment with the sleeve 18 and shaft 16. The fabric shaft may now bewithdrawn from the ring 35 and this will complete its disengagement fromthe machine. lVhile the fabric shaft was being pushed to the left, asshown in Figure 2, it pressed on the end of the shaft 26 and caused thelatter shaft to shift in the bearing against the resistance of thespring 31, so that. the parts were moved bacl: substantially as shown atthe left in Figure 2. l/Vhen the fabric shaft is disengaged from thering '35 the shaft 26 moves forwardly again until the collar 29 restsagainst the bearing 25 as shown in Figure 3. A cardboard tube such as isused for the winding core for the fabric may now be slid over the fabricshaft, whereupon the latter with the core may be returned to the windingmachine. For the return operation one end of the fabric shaft isinserted into the ring while the latter is turned at an angle to theaxis of the shaft 26 and then the fabric shaft moved to a positionapproximately in line with the shaft 26 and it is pushed to the left toslide the shaft 26 in opposition to the spring 31 the same as during theremoval operation.

When the end 21 of the fabric shaft has I been moved back sufficientlyto clearthe end of the sleeve 18, the fabric shaft is straightened tolie in line with the axis of the shafts 26 and 16. The fabric shaft isthen allowed to move to the right under the pressure of the spring 31,so that the flattened end 21 enters the end of the sleeve 18 and passesinto the slot 20 of the shaft 16. The end of the strip of fabric whichis to be wound is now attached to the core held on the fabric shaft andthe source of power is started so that the operating force istransmitted through the several driving members 7 to 15 in Figure l andthe shaft 16 is caused to revolve. The sleeve 18 and the slotted end ofthe shaft 16 revolve together and cause the fabric shaft to be revolvedwith them. The opposite or left hand end of the fabric shaft revolves inthe bushing 38 because the shaft 26 does not partake of any revolvingmotion. After the fabric has ii been wound upon the core and around thefabric shaft to the point where a desired bodv or coil of fabric hasbeen built up on the core. the body of fabric together with the fabricshaft may be removed from the machine in substantially the same manneras above described in connection with the removal of the fabric shaftalone. In removing the fabric and shaft the operator merely has to graspthe body of fabric and push it to the left to disengage the end 21 ofthe fabric shaft from the sleeve 18 and from the slotted end of theshaft 16 swing the fabric shaft with the ring 35 and then move the bodyof fabric with the fabric shaft until the latter disengages from thering 35. It will be noted that in this operation the operator can useboth hands to manipulate the body of fabric and that the release of thefabric shaft is controi'ed entirely through the manipulation of the bodyof fabric.
